The RZ/V2H USB2 PHY requires control of the VBUS selection line
(VBENCTL) through a mux controller described in the device tree as
"mux-controller". This change adds support for registering the
rzv2h-usb-vbenctl auxiliary driver during probe.
This enables proper management of USB2.0 VBUS source selection on
platforms using the RZ/V2H SoC.
